主题：如何上一条、下一条等与相应的底层表含接？谢谢

Select Case e.Sender.Name
    Case "btnPrev"
        CurrentTable.Position = CurrentTable.Position - 1
    Case "btnNext"
        CurrentTable.Position = CurrentTable.Position + 1
    Case "btnFirst"
        CurrentTable.Position = 0
    Case "btnLast"
        CurrentTable.Position = CurrentTable.Rows.Count -1
End Select

目的是想让上一条等作用于底层表，谢谢
